Just removed these and they have about 40k (give or take) on them. 441+ RR shocks. Swift springs with helper springs. Not 100% sure on rates. I'll see if I can find a part number on the springs. Feal top mounts. 30ish clicks of adjustability for rebound. One pair of remote adjustment knob/cables. Might could use new bump stops? Fine condition, just stiffer than I want to daily. Good track setup. They are about $3k new. Make offer. Located in Atlanta.
